GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 274,733, dated March27, 1883.

Application filed February 16, 1883. (No model.)

To all whom it may concern 1 Be itknown that 1, JAMES S. DE PALOS, acitizen of the United States, residing in the city, county, and State ofNew York, have in- 5 vented certain new and useful Improvements inGas-Regulators, of which thefollowing is a specification.

It is Well known that in certain diaphragm gas-regulators it isnecessary, in order that to the diaphragm shall have free movement, toprovide an opening above the upper surface of the diaphragm to allow theproper movement or displacement of air, and that in such regulators theair escaping from within carries with it a disagreeable odor, resultingfrom its contact with gas-tainted interior surfaces, or with the oil orgreasensed in connection with the diaphragm, or with other extraneousmatter. e In Patent N 0. 268,368 granted November 28, 1882, to Griffin.S. Lacey,is found an invention intended to permit the air above thediaphragm, and in contact therewith, to have the requisite movement, thetainted air being separated from the airof theroom or apartment by meansof a seal comprising an inverted cup covering an aperture leading fromabove the diaphragm, the cup rising and falling within a body of liquid,after the manner of the ordinary gas- 0 ometer used by gas-works.Theinvention described in the said patent to Lacey effects most of thevaluable results sought for in a regulator of this class; and the objectof my invention is to obtain the same advantageous 3 5 results in anincreased degree'by means which shall be more positive in their actionand dependent upon the movement of the valve governing the inflow of gasto the regulator, which provisions are found in practice to produce aofflame of greater steadiness, and to give other desirable effects. if

In the accompanying drawings, Figure 1 represents a vertical centralsection of the invention. Fig. 2 is a sectional plan on the linewmofFig. 1 1i Similar letters of reference indicate similar parts inboth views.

A represents the lower portion of the case of the gas-regulator, and Athe upper portion,

5:: these parts being united by screws a.

.which is screwed into the part 0 of the lower B is the gas-inlet pipe,connecting with the meter, and G the outletleading to the burners.

D is' a plate having perforations, the aggregate area of which issufficient to' admit the requisitesupply of gas to the valve under themaximum pressure exerted in the mains.

E is the valve, which has vertical movement above the perforated plateD, and b its seat,

portion, A, of the case.

The perforated plate D is confined between the lower surface, d, of thesaid part A and the upper surface of the detachable flange 0, intowhichthe inlet-pipe Bis screwed. The valve E is provided with a stem, 6,to which 6 is attached a disk, 6, sustaining the central portion of theflexible diaphragm E. The outer edge or perimeter of the diaphragm restsupon the annular surface a of the case A. A gasket, a, is placed aroundthe edge of the diaphragm, on which gasket a metal ring, a, is placed.The projections 12, formed upon the under side of the upper portion, A(,of the casing,,rest upon the metal ringal'i, and when the two parts Aand A are held together by the screws a the periphery of the diaphragmisheld to its seat in a manner preventing any upward escape of gas. Abovethe center of the diaphragm is a second disk, 0', also slipped over thestem 6. The upper end of the stem 0 is threaded, and the disk 6', havingbeen placed over the stem, is clamped in place and in contact with thediaphragm by means of a nut, c, which rests upon a leather washer, c,for forming a tight joint.

F is an inverted cup, through the center of which passes a rod, f,having a screw-coupling,f, which connects with the upper threaded end ofthe valve-stem e. The cup F is held between the nut f and screw-collarf,and c is vertically adjustable.

G is a liquid-receptacle having a central vertical pipe, g, and aflange, g, which flange seats upon the top of theupper part, A, of thecase.

G is the screw-cap of the liquid-receptacle, in the top of which is anaperture, h, which unites with minute lateral apertures h, formed in theprojection hf on the cap. The apertures h allow the air confined abovethe liquid free JCO movement, while it is apparent that the liquidsealisolates it from the'body of air in contact with any gas-tainted part ofthe interior of the regulator. The liquid-receptacle G is madeattachable to and detachable from the upper part of the case, A, in anysuitable manner. The diameter of the liquid-receptacle is some whatgreater than that of the inverted cup F, so that when the latter isplaced concentrically of the receptacle an annular space is providedbetweenthe two parts. The cup may be adjusted to the required depth inthe liquid by means of its screw-rod attachment. It will be seen that asthe valve E rises and falls on the variation in pressure of the inflowof gas the inverted cup F rises and falls with it in the liquid-space,giving free movement to the body of air above the diaphragm, theliquid-seal we I venting the escapeinto the room of any air tainted bycontact with the interior of the regulator. The movement of the cup F istherefore compulsory with that of the valve, and the movement of thevalve, due to variations of pressure under it, is also communicated tothe inverted cup. The displacement or movement of air above thediaphragm is therefore the same as that of the gas below it, thusequalizing and steadying the movement of the valve and diaphragm andpreventing any fluttering or irregular action of the valve.

By employing the devices constituting my invention the steadiness of theflame is insured,

this desirable result depending almost excluknown. Neither do I limitmyself to the carrying out of my invention, or the method form ing apart thereof, by the special devices hereinbefore set forth; but,

Having described my invention, I claim- 1. The method hereinbeforedescribed of preventing the escape of gaseous or unpleasant odors from adiaphragm gas-regulator,'an d of equalizin g the action of the valve andstead ying the flame, which consists in sealing a body of air above thediaphragm, and effecting its displacementcoincidentally with themovement of the valve, substantially in the manner set as set forth.

4. In a diaphragm gas-regulator, a casing having a liquid-receptaclewith a perforated cap, combined with aninverted cup, a gas-regulatingvalve, and a connection between said cup and valve, substantially as setforth.

5. In a diaphragm gas-regulator, the combination, with aregulating-valve and its stem,

of a liquid-receptacle, and inverted cup enterin g the same, and anadjustable connection between said valve and cup, substantially as setforth.

In testimony whereof I have hereunto set my hand this 12th day ofFebruary, 1883.
